I installed Ivan on my laptop just now, but during launch it suddenly exits after having loaded all mods with the following information: Code: [11:29:11] [Client thread/INFO]: Injecting external mods into class path... [11:29:11] [Client thread/INFO]: Discovering mods on class path... [11:29:11] [Client thread/INFO]: Generating new Event Handler Proxy Class com.mumfrey.liteloader.core.event.EventProxy [11:29:11] [Client thread/INFO]: Successfully generated event handler proxy class with 63 handlers(s) and 63 total invokations [xcb] Unknown request in queue while dequeuing [xcb] Most likely this is a multi-threaded client and XInitThreads has not been called [xcb] Aborting, sorry about that. java: xcb_io.c:179: dequeue_pending_request: Zusicherung »!xcb_xlib_unknown_req_in_deq« nicht erfüllt. Process ended with code: 134 Here is the full log. I have Java 8 64-bit installed and up-to-date. It's Oracle Java too, not OpenJDK, as I'm sure someone is going to point that out. Otherwise, I'm running Arch Linux, Kernel 4.5.1-1, all software up-to-date.
